Notes

Fermentation Option: This recipe offers the flexibility of a long ferment. Letting the batter rest allows the sourdough to develop more flavor. If you choose this method, remember to not add the baking soda until just before baking.
If you prefer a thicker cake, you could split the batter between two round cake pans. Just be sure to adjust the baking time accordingly, checking for doneness a few minutes earlier. Then cool before frosting.
Serving: A sprinkle of sea salt on top of the frosted cake adds a nice contrast to the sweetness.
